This is the ic Iuse. TL494
Duty cycle adjust and risetime of 100nsec
Here is a 12k low quality picture of the circuit

@nvisser

give us something with a 555 if possible. There will be a lot of blown oscillators until we finish our job.

In the beginning I have blown only MOSFETs, a lot of them, now as Im "cleverer", Im blowing oscillators. This is ....

Here is a better picture used by JL naudin on the meg
The idea of this post is to show how he used the TL494 as oscilator

The 555 are realy outdated and the tl494 cost about nothing and is easier to built. You can adjust the duty cycly by changing the voltage on pin4 between 0 and 3.3v with a voltage divider ( resistor and pot) or with a 3.6v zener, 820 ohm resistor and 2k pot like in my first drawing
The problem with the 555 circuits is that when you adjust the duty cycle you also change the frequency. Very annoying!
On the TL494 ,Pins 9 and 10 give you opposite outputs as in JL Naudins circuit or if you use it it as in the first drawing you connect 8 and 11 together as output and use a 1k pullup resistor to 12v. Pin 9 and 12 than connect to ground
You should really use mosfet drivers like mc 33151 or Tc4420. It will switch your mosfets fully on and also switch very quick which prevents overheating of fets

Hello Otto,

this is the one i will use for my oscillators for testing

later i thing this will be the small solution.

Have you noticed any charging or interference with adjascent circuits or conductors?

this was a common problem a very long time ago:

Is that vibration released into the air ?

Sauron posted the little black video transformer.

Quote: The little transformer is made in this way:
a quadratic spool, inside diameter is 12mm, 1/2", height maybe 1"
first wound primary wire diameter 0,5mm = AWG 24, lenght 10m= 30 ft.
over the primary is the secondary
wire diameter is 0,8mm = AWG 20
 Hi Otto
Can you give us the number of turns (or lenght)  on the secondary please

Hello all,

@nvisser

If you use a MOSFET driver I think there would NOT be a vibration!! We need a capacitive coupling between the oscillator, the MOSFET and the coils.

@rensseak

thanks a lot. I will try it. If you also want to build it you have to change the cap 10nF or the other ot both or use just 1 with 470pF.

@Grumpy

I didnt try it but....

After over 10 hours in front of my PC I have to go.

Otto

who pays you?

OMG the secret has been revealed .... NOT !

The TPU will die soon enough , I can feel it . This is the final speculative bubble before the big crash .

tach Otto,

demnächst kommt ein kleines Paket von Conrad  ;D  bei mir an, dann kanns losgehen. Allerdings baue ich mir die Teile mit Sechsfachschalter und die Kondensatoren habe ich so wie in deiner Schaltung gewählt (4,7µF - 470nF - 47nF - 4,7nF und die letzten beiden mit 470pF u. 47pF). Die 1k Widerstände habe ich mit 2k5 Potis ersetzt um etwas feiner einstellen können. Bei dieser Gelegenheit noch ne Frage, muß es ein Edding sein.

@all

there is nothing special what i wrote, sorry

Norbert

do you see ripple on falling slope of square wave signal at mosfet ? disruptive discharge ?

Hi Otto
I need to ask you agian what this circuit does so you can claim that you solved the TPU secret?

Hello all,

@nvisser

at a frequensy at say 250kHz the "show" starts: very slow collapses. In the first moment when I saw it, I touhgt a capacitor is discharged into the coils, but there was no cap connected!
Then I tuned the frequency to a lower value and the frequency of the collapses rised. I never saw this before.
Then I connected a 2. oscillator and a 2. MOSFET to try it with 2 frequencies.

And then I was "clever" and used 2 frequencies of the same value. Veeeery nice. I knew that there could be a disaster, but I was not fast enough. The output resistors of my 2 oscillators are blown.

After I fixed them I was working a lot on the frequencies, made a lot of setups.....and the I found something that I DONT WANT to post.

Its on you all to find out what I saw.

I have now really not much time so ....tomorrow.

Otto
